Ethanol Subsidies Continue Amid Growing Concerns Over Sustainability

The federal government has been subsidizing the ethanol industry for nearly five decades. Since its inception, ethanol subsidies have taken various forms, including production tax credits, biofuel mandates, infrastructure subsidies, and grants for facility upgrades. The most recent development is the One Big Beautiful Bill Act (OBBBA) of 2025, which increased ethanol tax breaks by broadening eligibility for the Section 45Z Clean Fuel Production Credit.

This move potentially allows corn ethanol and other food-based biofuels to qualify. However, critics argue that these subsidies have distorted the marketplace and circumvented lawmakers' intentions. The elimination of certain ethanol subsidies over a decade ago was seen as a step in the right direction, but subsequent administrations have added new subsidies and special interest policies.

The 15 percent ethanol blend, known as E15, has been a contentious issue in recent years. Despite its potential benefits, many experts question the long-term sustainability of corn-based biofuels due to concerns over food prices and environmental impact.
